To the inner side faces of each of the flanges 16 a vertically extending channel bar 19 is welded or otherwise rigidly fixed.

Inner and outer sash frames 20 and 21 respectively, are also in the form of light metal castings, each of said frames including the opposite vertical side bars 22 connected by top and bottom rails 23 and 24 respectively. Each of the top rails includes a plate or bar disposed in a vertical plane and having a web or flange 25 centrally projecting outwardly therefrom. The bottom rail of the lower inner sash isalso of the same form while the bottom rail of the upper sash consists of a plate or bar disposed in a horizontal plane and having an upstanding'flange 26 in spaced relation to its outer edge which is disposed in the plane of the top rail 23 of said sash and the side bars 22 thereof. The opposite side bars of each sash are further provided intermediate of their opposite edges with the outwardly extending webs or flanges inclicated at 27. These flanges'of said sashes are respectively slidably engaged inthe channel bars 7 and 19 respectively, of the window frame. In Fig. v2 of the drawings, I have shown the glass panes 28 secured in each sash against the outer faces of the vertically extending webs thereof in the conventional manner, as bythe use of putty. In Fig. 8 however, I have shown a continuous strip of asbestos or other fibrous material 29 engaged against the outer side of the glass pane at the marginal edges thereof and tightly compressed against the same to holdthe pane in place against theflanges of'the-sash frame by the angular metal strip 30, one flange of which is secured to the horizontal webs of the sash frame by suitable screws indicated at 31.

The sash cords or chains 32 for the respective sashes are mounted in the adjacent wall structure in the usual manner and connected at one of their ends to suitable'counterweights (not shown). The other ends of these sash cords are provided withthe hoo'ksindicated at 33 which. maybe detachably connected with the upper ends of the respective sashes. Thus, in Fig. 2 of the drawings, I have shown the top rail of the lower sash provided adjacent its opposite ends with openings through which hooks 33 are engaged while the top rail ofthe upper sash is provided with pins or studs indicatedat 34 with which the hooks can be detachably connected. For the purpose of holding the free ends of the sash cords when disconnected :from the sash frames, I may provide the eye-bolts, screws or :other suitable means indicated at 35 fixed in the wood moldings 15 to which the hooks 33 can be temporarily attached.

For the purpose of tightly holding the respective sashes against sliding movement relative to the window frame, I provide upon the inner side of each sash the pivoted plates 36 each of which is provided at oneend with a cam flange 37. lVhen these pivoted plates are manually moved in one direction, the edges of the cam flanges 37 ride against the inner sides of the flanges 14 on the opposite side bars 5 of the window frame and by frictional coaction therewith, urge the window sashes outwardly, thus causing tight frictional bearing pressure of the outer edges of theflanges27 on-said'sashes against the ihase walls of the channels in the flanges or bars -7 and 19 on the window frame. When both sashes are in closed'position, as seen iinFig. 1, the outer edge'of flange 23-. on the topof-the lower sash engages closely upon the upper side of the lowerlhorizontal ibar24seof the upper sash while the web 25 of the top-: rail-ton the upper sash'bearstightly against thelower edge of the outer wall-ofthetop bar 8Tinthe window frame. Thus, .a substantially water and air tight closure of-the openingthrongh the window frame-may be secured.

i For the purpose of 'holdingeither of the sashes in vertically adjusted position inthe frame so that ventilationmay be obtained, I provide the horizontally sliding latch bolts 36 on the opposite vertical barsofeach sash, said sash bars having suitable guide means such as screws 38 engaged in longitudinal slots 38 of the "latch bolts. Theupper edge of each latch bolt .is provided with longitudinally spaced cavities 39 in which a spring pressed ball 40 mountedin suitable housings 41 are adapted to engage andihold the sliding :9

latch bolts in their adjusted posit-ions. The outer end of each latch bolt terminates in a cylindrical stud or pin 42;- Thesecpins, when the latch bolts are shifted outwardly .are

adapted for engagement in the openings 17 and $18 of-the window-frame. I By providing a desired number of these openings suitably, spaced apart,.the sashes may thus be locked and held in various adjusted positions with agreater or less 'openingbetween one end-of the sash and the window-frame.

From the foregoing description, the-construction and several advantages of my invention will be clearly understood. It will be readily apparent that by simply moving the pivoted plates 36 to a disengaged position with respect to the flanges 14011 the window frame as shown at the left handsid-e of Fig. 1, and thendisengagingthe sash cord hooks 33 from the sash framcs,-said sashframes may be lifted and completelyremoved from the metallic window frame structure, asind-icated in dotted lines in Fig. 2-of the drawings. Thus, the entire sash can beimmersed in a suitable cleaning solution, and bothsides o'f'the glass ciao pane, as well as the parts of the metal sash frame quickly and thoroughly cleaned. The sash can then be again easily and quickly mounted in its operative position in the Window frame. Thus it becomes entirely unnecessary for one to risk life and limb by standing on the window sill outside of the window opening in order to wash the outer sides of the glass panes.

In the foregoing description, I have referred to an embodiment of my invention which I believe to be entirely practical for the purpose in View. It will also be seen that in view of the metallic construction of the frame and the window sashes, the parts thereof will be exceedingly durable, and since of course, they are unaffected by moisture or changes in temperature, these sashes will always slide freely in the frame structure, without binding. At the same time, however, these metal sashes can be very tightly locked in the window frame to exclude air and moisture when desired. It will of course, be apparent that the essential features of my present invention and the advantages thereof might likewise be secured in various other alternative structures, and I accordingly reserve the privilege of resorting to all such legitimate changes therein as may be fairly embodied within the spirit and scope of the invention as claimed.

I claim:
